Problems solved by technology

[0002] In the preparation process of rubber materials, in order to improve the wear resistance of rubber materials, inorganic fillers are usually added to them. In order to improve the compatibility of inorganic fillers The coupling agent is stirred and reacted, or reacted directly after pulverization, but the large-particle inorganic filler is prone to fatigue wear in the rubber material, which reduces the wear resistance of the material. When a large amount of small-particle materials are directly added, it is easy to agglomerate, which in turn affects the filler. Dispersion, resulting in a reduction in the reinforcing properties of rubber materials

Embodiment 1

[0027] In the preparation process of rubber materials, in order to improve its wear resistance, it is necessary to add modified wear-resistant fillers. In the preparation process of modified wear-resistant fillers, the present invention provides a split-feeding reactor in order to realize sufficient modification of fillers. The sub-feeding reactor includes a reaction tank 1, a top cover 2 is fixed on the top of the reaction tank 1, a first rotating shaft 3 is installed at the center of the surface of the installation top cover 2, and a crushing and stirring mechanism 4 is installed at the bottom of the first rotating shaft 3 , the top end is connected with the power output end of the first reduction motor, and the center of the surface where the top cover 2 is installed is integrally connected and fixed with a fixed cylinder 21. The interior of the fixed cylinder 21 is equipped with a multi-directional transmission mechanism 5, and the multi-directional transmission mechanism 5 ...

Embodiment 2

[0041] The preparation method of the organic carbon material is the same as in Example 1. According to the amount added in Example 1, the organic carbon material, diatomaceous earth and nano-alumina are added to the reaction kettle at the same time, and then deionized water is added thereto, and the silane distillate is added after stirring evenly. The joint agent kh-560 was stirred and mixed for 3 hours, and then the obtained material was filtered, washed and dried to obtain a modified wear-resistant filler.

Embodiment 3

[0043] The preparation method of the organic carbon material is the same as in Example 1. According to the amount added in Example 1, diatomite, organic carbon material, nano-alumina deionized water and silane coupling agent kh-560 are simultaneously removed from the lower side of the side wall of the reaction tank 1. Put it into the reaction tank 1 at the feed port, grind for 2 hours and then stir for 3 hours, filter, wash and dry the obtained material to obtain a modified wear-resistant filler.

Abstract

The invention discloses a preparation process of a wear-resistant rubber material. The preparation process is characterized by comprising the following concrete steps: adding nitrile rubber into an internal mixer, conducting plastifying for 2-3 minutes, then adding zinc oxide, zinc stearate, an anti-aging agent and a modified wear-resistant filler, performing mixing at 150 DEG C for 5 minutes, carrying out heat treatment, adding sulfur and an accelerator, carrying out thin-passing, performing batching-out, performing cooling at room temperature for 8 hours, and carrying out vulcanizing on a press vulcanizer to obtain the wear-resistant rubber material. Separate feeding reactors used in the invention can contain various different fillers at the same time, and the adding sequence of the different fillers can be automatically controlled through a power locking mechanism, so processing efficiency is improved; and filler particles are more uniform by controlling large-particle-size fillersto be crushed and ground firstly and then controlling small-particle-size fillers to be added, so the fillers can be uniformly dispersed in the rubber material, and the prepared rubber material is uniform in performance.

Description

technical field [0001] The invention belongs to the field of rubber material preparation and relates to a preparation process of wear-resistant rubber material. Background technique [0002] In the preparation process of rubber materials, in order to improve the wear resistance of rubber materials, inorganic fillers are usually added to them. In order to improve the compatibility of inorganic fillers The coupling agent is stirred and reacted, or reacted directly after pulverization, but the large-particle inorganic filler is prone to fatigue wear in the rubber material, which reduces the wear resistance of the material, and the material with small particles is easy to agglomerate when directly added in large quantities, thereby affecting the filler. Dispersion, resulting in the reduction of its reinforcing performance on rubber materials. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process for wear-resistant rubber m...
